DARK PATTERNS

When I read the article " How Amazon, EBay and other online stores try to trick you into buying" I was very interested. When I would look at stuff online for example "Shein" it would like cross off the original price and put a less cheaper price. I thought that was a very good deal, but I would never really not even end up buying  anything. I remember if you liked, signed up with an account it would give you coupons that were like $5 or up to $20 off , when you purchased like $50 or more on any items. It looks like a good deal but it really isn't. I knew they were already tricking people so that they could make more money, but I mean every store does that so it didn't really bother me.
